A statistic is used to estimate an unknown parameter. A parameter is used to estimate an unknown statistic. Statistics can change from sample to sample. 99.For X~N(1, 12), find the probability P(X=5). 0 .1 .01 .98 100.The length of human pregnancies is approximately normal with mean 266 days and standard deviation 16 days.

Research the changes in the number of cellular phones and personal computers in the United States between 1980 and 2000. First estimate, then use graphing calculators to decide whether the linear, quadratic, or exponential model is appropriate in each case. Compare growth rates and predict future changes in the use of each item.

The estimate of the repeatability variance r2 is (19) where (20) is the average of the estimated within laboratory variance of the labotratories. The expectation of sri2 is , (21) i.e. it is biased; its bias is corrected by multiplication with n/(n-1), as in the formula for sr2. The estimate of the between laboratory variance L2 is. (22)

There is a fallacy in this belief because wrongly specified model can provide acceptable residuals, and even with poorly estimated model parameters. This is the reason why we must examine the adequacy of the model parameters estimators. Hypothesis Testing in Linear Regression

Least squares is approximating the conditional mean function. To see this effect more clearly, the figure below plots the estimated values of the conditional mean function using the maximum likelihood estimates (bold curve) and the predicted values from the linear regression. You can see how the linear model is approximating the nonlinear one.
